For the third time this year my grafted Lophophora williamsii (SB 854; Starr Co, Tx) is flowering – quite an accomplishment from a plant only 18 months from seed (sowed February 29, 2004). This flower was also self-pollinated.

My grafted Lophophora williamsii (SB 854; Starr Co, Tx) is flowering again (and yet another bud is in the works). Once again I had to self-pollinate the flower since none of my other plants are blooming.

Growth will tear us apart
The scion is growing so hard you can practically hear the epidermis squeaking. A couple of days ago it gave in to the pressure and burst – maybe triggered by the plant “rearranging itself”, starting to grow more ribs. The scion has grown to a width of 5 cm (~1.97’’), excluding the offshoots.

The Echinopsis (Trichocereus) pachanoi stock refuses to give up the fight and is stubbornly growing yet another offshoot.

The sowing bags have been open for the last week, and yesterday the seedling plants were removed from the bags and fully exposed to the real world environment. The 30+ Obregonia denegrii (VVZ 163; San Vicente, Tamaulipas) seedlings are growing vigorously, and I’m already wondering how to find room for all the plants ;-)

The 6 Ariocarpus fissuratus (PP 176; Big Bend, Texas) seedlings also started out convincingly but after growing a couple of diminutive tubercles each, their growth grinded to a halt. I’m a bit disappointed with the germination rate of these A. fissuratus seeds and will probably try again next year with seeds from a different supplier.

The main shoot of my Cylindropuntia tunicata was maimed too. A search of the cacti revealed a great green bush-cricket (Tettigonia viridissima) hiding among the plants. I took the mug shot below before releasing the suspected culprit outdoors.

The harm is not too great and I expect the plants to fully recuperate from the damage.

I finally got around and ordered my ‘early subscriber’ copy of the The New Cactus Lexicon. The lexicon is prepared on behalf of the International Cactaceae Systematics Group (ICSG) by David Hunt et al. and will publish by March 2006 at the latest. The invitation to subscribe early expires at August 31, 2005. A full prospectus and order form is available online.

“Planned as a successor to Backeberg's Cactus Lexicon, The New Cactus Lexicon will be the most scientifically authoritative conspectus of the Cactaceae published for nearly a century. It will be comprehensively illustrated in colour and is confidently expected to become the benchmark reference for all those with amateur or professional interests in the diversity, identification and conservation of cacti.”

I trust the lexicon will have in-depth coverage of Acharagma, Lophophora, Obregonia, Strombocactus etc. ;-)

Update - July 31, 2006
The lexicon arrived a couple of days ago – I’ll get back with more information when I’ve had a chance to study the books.

About Me

Information on the peyote cactus et cetera. The primary focus of the Lophophora Blog is small Mexican cactus species like Lophophora (peyote), Obregonia (artichoke cactus), Acharagma, Ariocarpus (living rock), and Strombocactus but occasionally other subjects will be dealt with as well. Welcome to the Lophoforum and happy growing :-)
